Abstract: 

Digital Signal Processing (DSP) is a basis for FPGA designs and is the core technology of many electronics devices. However, it requires study at a practical level in order to complete its deployment. This thesis examines the practical implementation of different DSP algorithms using FPGA devices. In our first contribution, we investigate the performance of a quadrature demodulator when implemented on FPGA. In the second contribution, we design a switch in the transmitter of wireless system operating under orthogonal frequency division multiplexing (OFDM). Here we devise a simple FPGA design to utilize feedback from the receiver aimed at reducing interference present in the system. In the third contribution, we present an efficient FPGA design for real-time convolution/correlation, as an essential component in the electronics in most wireless systems. Throughout the thesis, our emphasis is on the practical aspects of DSP.
